Q - Should we request Belcarra's built-in DHCP for our driver?
A . The built-in DHCP server is suitable for PAN (personal area network) devices. This applies to all peripherals EXCEPT infrastructure devices, i.e. peripherals explicitly designed to provide access to a remote network, such as a satellite connection. Such networks will have their own management machinery and will not want Belcarra's built-in DHCP server.
So: PAN device (most cases): enable built-in DHCP server Infrastructure device (network access device): disable built-in DHCP server.
